Patented June 18, 1957 Inthe practice of my invention, a pair of vertical mas- 'ter frame'members 16 are secured to the outside of the window frame 10 at each side thereof. Each master frame member 16 includes a fiat portion 17 (Fig. 4) adapted to lie flush with the outer face of the frame 10 and integrally formed along its outer longitudinal edge .bevelled portion 19 which extends outwardly from the frame 10 which is in turn integrally formed with a flange 20 spaced from and substantially parallel to the outer face of the frame 10. A guide channel member 21 is integrally formed on the inner face of the flange 24) (Fig. 4) and extends inwardly therefrom between the sides of frame 10 where it is integrally formed with a flange 22 extending substantially parallel to the outer face of the frame 10 and abutting the inside of the latter. The flange 22 along the edge thereof in abutment with the inside of frame 10 is integrally formed with a rib 23 and a second rib 24 intermediate the rib 23 and guide member 21. It will-be noted that the edge of the flange 22 remote from rib 23 extends towards the center of the window beyond the outer face of guide member 21, providing with the latter and the flange 20 a three-sided guide channel.

A removable track .25 (Fig. 5) fits snugly within each of the master frame members '16 and includes an elongated plate 26 adapted to lie flush with the outer face of the guide member 21, the outer face of each of the plates '26 being integrally formed with the laterally spaced,'lon- .gitudinally extending tracks 27, 28, 29 and 31 It will be noted that the track 27 is formed flush with the inner longitudinal edge of plate 26 while the track 30 is spaced inwardly from the outer longitudinal edge of plate 26.

An upper storm sash 31 and a lower storm sash 32 are provided for sliding movement in a vertical direction between the tracks 25; as shown in Fig.2, the lower storm sash 32 is of a greater heightthan the upper sash 31.

The upper sash 31 includes an upper horizontal portion 33 (Fig.2) and a lower horizontal portion 34 connected attheir ends by vertical portions'35 (Fig. 7), the portions 35being of substantially H-shaped cross section.

As shown in Fig. 7, the vertical portions 35 of H- shaped cross section provide outer, vertically extending grooves 36 which cooperate with corresponding grooves provided on thehorizontal portions 34-and 33 to fixedly mount the window glass 37, the H-shaped members 35 also providing inner grooves 38which receive therewithin the laterally aligned tracks 29. The double edges of the members 35 adjacent the plate 26 are integrally formed withinwardly extending ribs 39 which embrace the tracks 29 -on.each side thereof, secondary ribs 40 being provided intermediate the ribs 39 and groove 36. The upper storm sash .31, thus constructed, is adapted to slide vertically to any position upon tracks 29, the sash being retained in any desired position by means of a curved leaf spring 41 secured at one end within a slot 42 in portion 35 .(Fig. 7), the other end of spring 41 being provided with a slot 43 which'st-raddles the rib 40. The leaf spring 41 is also provided with a central longitudinal slot 44 which straddles theopposite rib 40. .Thus, the leaf spring 41 willnbe at all timesin tensional engagement with one face of the track 29, whereby to retain the sash '31 in the desired vertical position until forced upwardly or downwardly.

The lower=storm sash 32 is of a similar construction to the sash 31 and includes the upper and lower horizontal portions 44 and 45, respectively (Fig. 2) connected by vertical portions 46. As shown in Fig. 4, the vertical portions 46 are of H-shaped cross section and provide inner grooves 47 which cooperate with corresponding grooves provided in the upper and lower horizontal portions 44 and 45, respectively, to fixedly mount the 'window glass 48, the H-shaped members 46 providing outer grooves 49 which receive therewithin the tracks 27. A

' corresponding groove provided on the inner face of the horizontal portion 34 of upper sash 31 along its upper edge and which cooperates with weather stripping 54 and 55 provided on the adjacent faces of the horizontal portions 34 and 44 respectively whereby to substantially seal off the entrance of wind. This arrangement is more clearly shown in Fig. 3 wherein the upper and lower sashes and 32 are mounted on the tracks 29 and 28 respectively.

As shown in Fig. 5, the plate 26 is provided 'with inwardly stamped stops 57 which limit the extreme positions of the sashes.

Thus, the storm sashes 25 and 32 (arranged either as shown in Fig. 2 or in Fig. 3) may occupy the closed positions shown or any position intermediaite the ends of the tracks 25.

As shown in Fig. 2, upper and lower window screen sashes 58 and 59, respectively, are provided for vertical movement intermediate the tracks 25. The lower window screen sash 59 includes the upper and lower horizontal portions 59 and 60 connected by the vertical portions 61 similar in cross section to the vertical portions and 46 of sashes 25 and 32 respectively. The H-shaped members 61 provide outer grooves 62 which cooperate with corresponding grooves provided in the horizontal members 59' and 60 to fixedly mount the frame 63 of a wire screen 64. The double edges of the members 61 are provided with the ribs 65 which embrace the tracks 29 on each side, ribs 66 being provided intermediate the ribs 65 and grooves 62. Leaf spring 67 identical to leaf springs 41 and 50 straddle the ribs 66 whereby to retain the screen sash 58 at any desired vertical position.

The upper window screen sash 58 is identical in construction with the lower window screen sash 59 and includes the horizontal portions 68 and 69 (Fig. 2) connected at their ends by the vertical portions 70 identical in cross section with the vertical portions 61. The H- shaped portions 70 provide inner grooves which receive therewithin the track 30, the portions 70 also providing the outer grooves which cooperate with corresponding grooves provided in the horizontal portions 68 and 69 to fixedly mount the frame 71 of the wire screen 72. A leaf spring 73 (Fig. 2) identical to the leaf spring 67 retains the upper window screen sash 58 at any desired position.

When the window screen sashes 58 and 59 are arranged on tracks 30 and 29 (Fig. 2) the adjacent facesof the horizontal portions 59' and 69 will be provided with Weather stripping similar to that described in connection with the storm sashes 25 and 32. Such weather stripping may, however, be eliminated when the window screen sashes are arranged on tracks 30 and 27, as shown in Fig. 3.

As shown in Fig. 2, the window screen sashes 58 and 59 may be removed upwardly past heading 11, if desired.

As shown in Fig. 2, the tracks 25 consist of upper and lower portions, the upper portions being fixed while the lower portions are removable.

It should now be apparent that there has been provided a storm sash and window screen structure including double storm sashes and double window screen sashes which may occupy all positions within the limits of their vertical tracks, the invention eliminating the necessity of having to remove storm sashes for summer storage and screen sashes for winter'storage. It should also be apparent that there has been provided a storm sash and window screen structure including double storm sashes-and double window screen sashes-which are mounted in a single frame which may be permanently mounted upon the outside of the conventional window frame without marring in any manner the appearance of the building.

While various changes may be made in the detail con- I struction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
